I have the following data representing the normal displacement caused by load applied at the middle cross section of a cylinder, normal to the cylinder surface. Only the middle cross section cut is shown (which is what I need):
I've made the data available here.
I don't know exactly how would it the best fitting function for this, but I guess Mathematica has some functionality which would allow me to find a good fitting function, I just don't know which functionality would it be.
I would very much appreaciate any help!
